6. PIN DESCRIPTION

TABLE 1 – PIN DESCRIPTION

Pin Name

I/O

Description

INC

I

Increment Control. A High-Low transition of INC when

CS

is low will move the wiper up or down for one

increment based on the U/ D input

U/ D

I

Up/Down control Input. High state will cause the wiper to

move to the VB terminal, Low state to the VA terminal

VA

-

High terminal of WinPot

VSS

-

Ground pin, logic ground reference

VDD

-

Power Supply

CS

I

Chip Select. When CS is HIGH, the part is deselected

and the device will be in the standby mode. CS LOW

enables the part, placing it in the active power mode

VB

-

Low terminal of WinPot

VW

O

Wiper terminal of WinPot (can be buffered), its position on

the resistor array is controlled by the inputs on INC , U/ D ,

and CS
